SIA has been around since 2014, "whatever doesn't kill you makes you stronger", SIA has survived, it is strong, it is very well regarded, and the tech is fantastic.
Of course Sia already survive till today, but community and miners also need something good from Sia as part of their innovation. From their public feature roadmap, i don't see any good improvement to help Sia get their more demand. If its happen for a long time, what Litcoingva says will increased and the community lost in faith for this project. Decreasing and losing community and miners will be hard for the team to fixed it.
